It is transferred from 0 to the mounting table 26. The tray 21 is not limited to the one made of carbon fiber, but may be made of synthetic resin or metal.

The moving speed adjusting device 45 for the tray push cylinder 22 will be described below. The moving speed adjusting device 45 comprises the position switches 24 and 25 and a configuration which will be described in detail below. That is, as shown in FIG. 1 and the like, the position switch 27 provided at a desired position of the movement stroke of the lot 23 of the cylinder 22 and the syringe 22 shown in FIG.

The solenoid valve 48 is directly connected to an air source (not shown), and the solenoid valve 49 is a precision regulator 50.
Is connected to the air source via.

As a result, the controller operates the solenoid valve 48 when the tray is supplied (from the state of FIG. 3 to the state of FIG. 7).
Condition) When a desired air pressure is supplied from the air source to the cylinder 22 via the speed controller 46, the lot 23 is moved forward and the lot end is moved to a position where the position switch 27 is turned on instead of the position switch 24. The control device actuates the solenoid valve 49 (see FIG. 8) to adjust the air pressure adjusted by the precision regulator 50 from the air source to the desired air pressure (air pressure lower than the air pressure supplied via the solenoid valve 48). The lot 23 is supplied to the syringe 22 in the direction of returning the lot 23 through the. Therefore, the movement speed of the lot 23 after the position switch 27 is turned on is moved by the air pressure reduced by the air pressure supplied from the solenoid valve 49 from the air pressure supplied from the solenoid valve 46, and until then. It is moved at a slower speed than. Then, as shown in FIG. 9, the solenoid valve 48 is turned off and the lot 23 is returned and operated.

The tray presence / absence detecting device 29 for the tray 21 on the mounting table 26 will be described below. A tray positioning cylinder 30 is positioned by pushing the tray 21 to the other end while the contact rod 32 attached to the lot 31 is moved forward to abut the side surface of the tray 21 on the mounting table 26. . At this time, when the lot end (not shown) is in the retracted position, the position switch 33 composed of a proximity sensor is turned on (see FIG. 6), and when moved forward for positioning, the position switch 34 replaces the switch 33. When it is turned on, it is detected that the positioning is completed. Further, when the position switch 34 is turned on once and then turned off again during the forward movement, as shown in FIG. 10, when the tray 21 is not placed on the placing table 26, the contact rod 32 moves to the tray. Two
This is because the lot end moves past the position where the position switch 34 is arranged, and the lot end moves past the position where the position switch 34 abuts. Therefore, the control device (not shown) in the operation box 40, which will be described later, determines from the state of the switch 34. Then, the operator is notified via an alarm device (not shown) and the device is stopped.

A heat sink storage device 36 takes out the heat sink 3 to which the pellets are pressure-bonded from a dedicated jig through an arm portion (not shown), and places the tray 21 on the mounting table 26.
Reprinted to. Tray 21 full of heat sink 3
Is a tray storage magazine 37 by a transfer device (not shown).
And is returned to the tray supply magazine 20 by a circulation mechanism (not shown).

38 is all the heat sinks 3 that have been stored
In the storage lifter for collecting the taken out special jig, the collected special jig is returned to the supply lifter 6 by a circulation mechanism (not shown). First, the operator operates the operation box 4
When the power mounter 1 is started via 0, the heat sink 3 is supplied from the parts feeder 2 onto the heat sink supply table 4.

Further, a dedicated jig is supplied from the supply lifter 6 onto the conveyor 7, and the heat sink 3 is transferred to the dedicated jig via the arm portion of the heat sink supply device 8.
Subsequently, the dedicated jig on which the plurality of heat sinks 3 are placed is intermittently fed by the conveyor 7 and
The solder foil is successively adhered to the surface of the heat sink 3 at the preform position.

Then, the pellets which are pushed up one by one from the wafer sheet 13 by the push-up pins are picked up by the arm portion of the pellet transfer device 14 and transferred onto the positioning table 15, and a pair of positioning claws are placed on the positioning table 15. The pellets thus positioned are picked up by the bonding head 18 of the bonding device 17 and are pressure-bonded onto the solder foil of the heat sink 3 in the dedicated jig that has been conveyed to the bonding work position by the conveyor 7.

The heat sink 3 to which the pellets are pressed is
The lot 23 of the tray push cylinder 22 is moved forward from the position where the lot end 23A is detected by the position switch 24 (see FIGS. 3 and 4) to the position detected by the position switch 25, whereby the lot 23 of the tray push cylinder 22 moves from the state of FIG. As shown in FIG. 6, the arm portion of the heat sink storage device 36 transfers the tray 21 to the tray 21 transferred from the tray supply magazine 20 to the mounting table 26. At this time, the solenoid valve 48 is operated by the control device (from the state of FIG. 3 to the state of FIG. 7), the desired air pressure is supplied from the air source to the cylinder 22 via the speed controller 46, and the lot 23 is moved forward. When the lot end 23A is moved to a position where the position switch 27 is turned on instead of the position switch 24, the control device actuates the solenoid valve 49 (see FIG. 8) and the desired air pressure from the air source (see the above) is obtained by the precision regulator 50. (Air pressure less than the air pressure supplied via the solenoid valve 48)
The air pressure adjusted to 2 is supplied to the cylinder 22 through the speed controller 47 in the direction for returning the lot 23 as shown in FIG. As a result, the moving speed of the lot 23 after the position switch 27 is turned on is
The air pressure supplied from the solenoid valve 46 is moved by the air pressure reduced by the air pressure supplied from the solenoid valve 49, and the air pressure is moved at a lower speed than before.

Next, the tray 2 transferred onto the mounting table 26
1, the controller receives the signal that the position switch 25 is turned on, and the controller operates the tray positioning cylinder 30 so that the contact rod 32 is moved forward and the side surface of the tray 21 on the mounting table 26 is moved as shown in FIG. The tray 21 is positioned by pushing the tray 21 toward the other end while abutting on the section. Then, the control device receiving the ON signal of the position switch 34 judges that the positioning is completed, and causes the lot 23 of the tray push cylinder 22 to return to the operation as shown in FIG.

At this time, the tray 21 is placed on the mounting table 26.
If there is not, the position switch 34 turns ON once during forward movement and then turns OFF again, so the control device judges from the state of the switch 34, and notifies the operator through the notification device and To stop. Here, the description will be continued below assuming that the tray 21 is positioned and mounted on the mounting table 26. The heat sink 3 to which the pellets in the dedicated jig are pressure bonded is transferred to the tray 21 on the mounting table 25 by the arm portion of the heat sink storage device 36. Thereafter, the heat sink 3 is similarly transferred, and the tray 21 full of the heat sink 3 is stored in the tray storage magazine 37 by the transfer device. Further, the new tray 21 is transferred from the magazine 20 onto the mounting table 26, and the control device, which has determined from the ON signal of the position switch 34 that the positioning has been completed, operates the heat sink storage device 36 to move the heat sink 3 to the tray 21. Transfer to.
After that, the work is similarly continued.
